Title: SPC5777 MG1CS003 Disassembly.
Post by: PsiDOC on November 09, 2025, 11:00:13 PM
Looking for some suggestions on disassembling a Bosch MG1CS003 powered by the SPC5777M.
I have the .hex file but with no ram mappings of course.
I am getting some joy in IDA Pro, but it doesn't look right and memory locations are missing etc.
I am currently setting up in IDA Pro as a PPC, Big Endian, 32 bit VLE only. No r2 or r13 set to get the above.
Ghidra says nope every time no matter what settings I use.
What am I missing? Can anyone give me any pointers?
Also how do I find the r2 and r13 locarions?
Cheers.
